Minnesota Vikings: Offensive tackle
Multiple injuries at one position almost always bring big trouble—especially at a reactionary position like tackle. Much like how corners react to receivers, tackles react to edge rushers. And the tackles in Minnesota simply couldn't keep up in 2016. After Matt Kalil (right hip), Andre Smith (right elbow) and Jake Long (left Achilles) each went down before Thanksgiving, T.J. Clemmings (whose future is as a backup right tackle, at best) was forced to protect Sam Bradford's blind side. The Vikings had to overhaul their scheme just to hide him. With Kalil and Smith entering free agency (both may walk; Kalil was inconsistent and Smith is injury-prone), Minnesota must remake the position that killed this team.
